Subject: [PATCH v7 11/17] drm: rcar-du: Move rcar_du_vsp_plane_cleanup_fb()

Move rcar_du_vsp_plane_cleanup_fb() to RCar DU vsp lib so that
it can be shared by both RCar and RZ/G2L DU vsp drivers.

Signed-off-by: Biju Das <biju.das.jz@...renesas.com>
---
v6->v7:
 * Rebased to drm-tip.
v1->v6:
 * Rebased on drm-misc-next and DU-next.
v1:
 * Created the lib suggested by Laurent.
